Presentation
Cognitive impairment in a patient with poorly controlled hypertension.
Patient Data















Extensive high FLAIR and T2 changes through the supratentorial periventricular white matter in keeping with chronic small vessel ischemia. Old lacunar infarcts are seen at the supratentorial white matter and in the pons with ex vacuo ventriculomegaly.
Multiple punctate areas of susceptibility signal loss are seen on gradient echo mainly in the basal ganglia.
Case Discussion
MRI features are most consistent with hypertensive microangiopathy also called chronic hypertensive encephalopathy.
On imaging the main differential diagnosis is cerebral amyloid angiopathy which usually has a peripheral distribution, and tends to spare the basal ganglia and pons.
